Tire Pressure Sensor Fault in a Tesla Model 3

Common Causes of Tire Pressure Sensor Fault in a Tesla Model 3

  1. Low Tire Pressure: The TPMS will trigger an alert if any of your tires fall below the recommended pressure, which is typically 42 PSI for a Tesla Model 3. This is the most common cause of TPMS warnings.
  2. Sensor Issues After Tire Change: If you’ve recently replaced or rotated your tires, the system may need recalibration. Tesla’s TPMS might not instantly recognize the new tires or sensors, causing a fault.
  3. Sensor Damage or Failure: Though TPMS sensors are quite durable, they can still fail due to impacts, water damage, or wear over time. A faulty sensor may stop reporting accurate pressure readings.
  4. Software Glitch: Tesla’s software can occasionally experience bugs, causing false TPMS alerts. An over-the-air software update or a manual reset can often fix this.
  5. Environmental Factors: Extreme temperatures or altitude changes can trigger a false low-pressure warning. Tesla’s TPMS is highly sensitive to these changes.

How to Fix the Tire Pressure Sensor Fault in a Tesla Model 3:

  1. Check and Adjust Tire Pressure:
    • Start by checking the pressure in all four tires. The recommended pressure for the Tesla Model 3 is 42 PSI, though it may vary slightly depending on the tire type.
    • If underinflated, fill the tires to the proper PSI. You can check the pressure on your Tesla’s touchscreen.
  2. Reset the TPMS Sensors:
    • Go to the Controls menu on the Tesla’s touchscreen.
    • Navigate to Service > Tire Pressure Monitor > Reset Sensors.
    • Drive the car for about 10-15 minutes at speeds over 15 mph to allow the system to recalibrate.
  3. Check for Software Updates:
    • Ensure that your Tesla is running the latest software. If an update is available, it may resolve any false TPMS warnings.
    • Go to Software in the car’s menu and check for updates. Install if available.
  4. Replace Faulty Sensors:
    • If a sensor has failed, you’ll need to visit a Tesla service center where they can identify and replace the faulty sensor.
    • Unlike traditional cars, Tesla vehicles require specific sensors, and replacements may only be performed at authorized centers.
  5. Environmental Adjustments:
    • If you’ve driven in extreme weather or through high-altitude regions, the TPMS may show a false alert. Allow the tires to cool or adjust based on temperature changes to see if the warning goes away naturally.
